“适应” is a verb that means “adapt to (a condition or a need)” .
北极非常冷，我每天吃一桶冰激凌，就能适应那儿的温度了。
The North Pole is very cold. If I could eat one bucke of ice-cream every day, I would be able to adapt to the weather there.

(In) the future your child thought about doing what?
One day, I ask (my) son: “What do you want to be (when you) grow up?”
(My) son replied: “Dad, I want to be an Arctic explorer when I grow up.”
I was very pleased: “Great!”
(My) son (then) said: “I want to start training immediately.”
I was very surprised: “How (does one) train?”
(My) son replied: “The Arctic is very cold, I (shall) eat a bucket of ice cream every day, where(upon) I will be (able to) adopt to the temperature”.

When you were still young, did you know what want to be later?
One day, I asked my child, “When you grow up what do you want to be?”.
My child replied, “Papa I want to become a North Pole explorer”
I said “That’s great!”
My child continued “I will start immediately to train myself”
How odd I thought tis very strange: “How will you prepare yourself?”
My child said:” The North Pole is very cold, I will eat a bucket ice-cream each day,
so I get used to the temperature there.”
